JOHN AVERY, OF YONKERS, NEW YORK.

DEVICE FOR AND METHOD OF INSTALLING JOINT-FILLING MATERIAL IN CONCRETE OR OTHER TYPES OF PAVEMENT.

Patented An 26, 1919.

Application filed September 19, 1917. Serial No. 192,121.

To all whom it may concern:

Be it known that I, JOHN AVERY, a citizen of the United States, residing at Yonkers, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Devices for and Methods of Installing Joint-Filling Material in Concrete or other Types of Pave ment, of which the following is a specification.

My invention relates to a device or devices for and method of installing joint-filling material in concrete or other types of pavement.

The object of my invention is to produce a device which Will retain the joint-filler in proper position when the pavement is being laid.

A further object is an im roved method for properly placing jointlling material in concrete or other types of pavement.

The invention consists further in the novel devices and arrangements to be hereafter described and claimed for carrying out the above stated objects and such other objects as will appear from the following specification.

The invention is illustrated in certain preferred embodiments in the accompanying drawings, wherein Figure 1 is a plan view showing a joint filler held in position by a plurality of my devices.

Fig. 2 is a section on line 2--2 of Fig. 1, showing one of the devices partially in section.

Fig. 3 is a view similar to Fig. 2, but showing a modification.

Like characters of reference designate like parts in the figures of the drawing.

In the drawing 1 is a strip of filling material. This may be composed of any of the substances commonly used for filling joints in pavements. The filling strip is held in position bv one or more devices 2 secured at one end 3 to the filling strip by means of a suitable clamp 41:. This clamp firmly holds the filling strip. The anchoring device 2 is provided with an arched arm 5, at the other end of which is provided a means for holding the device and the filling strip in position. In Fig. 2 this is shown to be a suitable clamp 6, which, for the purcopies of this patent may be obtained for five cents each, by addressing the pose of anchoring the device, is clamped to a board 7 or other object.

In Fig. 3 I have shown a modification of the anchoring device, in which the opposite end of the arm 5' is provided with a spike or prong 8 having a driving head 9 for driving the spike into the ground and thus anchoring the device in position.

After the joint filler is held in position, the paving material is placed against the joint-filler. After this is done, the anchoriug devices 2 may be removed and used to hold other joint-fillers as the laying of the pavement progresses.

It will be seen that I have thus devised an improved method for placing joint filling material in concrete or other types of pavement so that they will retain their proper position in the finished pavement.

Other modifications of my method and devices might be made without departure from the principles of my invention.

I claim:

1. As an article of manufacture, a unitary device for holding a filler strip in position in the construction of a concrete pavement, comprising an arm arched to extend above the upper level of the pavement terminating in a depending clamp at one end adapted to engage the upper edge of the strip and hold it in vertical position, and a device at the other end below the surface of the pavement for positioning the device in the roadway whereby the filler strip may be held against lateral displacement by means of a plurality of said devices in any desired vertical position in the pavement.

2. As an article of manufacture, a unitary device for holding a filler strip in position in the construction of a concrete pavement, comprising an arm arched to extend above the upper level of the pavement with a depending clamp at one end adapted to engage the upper edge of the strip and hold it in vertical position, and a depending clamp at the other end, below the surface of the pavement and close to the ground, parallel to the first-mentioned clamp, for engaging the upper edge of a plank whereby the filler strip may be held against lateral displacement, by a plurality of said devices, in any desired vertical position in the pavement.
